Coding: Pros and Cons
nChannel or error-control coding is adding redundant  bits to detect only or detect and correct errors. nGoal: Increase the operational range, reduce error probability or reduce power transmission requirements. nTypical gains are in the range of 4-5 dB in SNR for BER and much better FER gains. Much higher gains are now possible with relatively little cost than other methods.
nSacrifice: Bit rate and/or complexity.
